The Diamond Casino Heist

The Diamond Casino Heist Walkthrough

The Diamond Casino & Resort has been taken over by the Duggans, Texan petrochem magnates who wrenched control from Tao Cheng and the Triads.

Georgina Cheng, Vice President of Cheng Holdings, wants to take the Duggans down, and she needs help to do it. Team up with her, and hacker genius Lester Crest, to plan and execute a heist like no other.
This heist has a variety of approach vectors, several opportunities for setup and prep missions, and objectives may change on the fly if things go wrong during the job.

Players must own an Arcade, which can be purchased from Maze Bank Foreclosures, and be registered as a VIP, CEO, or MC President to gain access to the Arcade setup mission. The setup mission must be completed to gain access to Heist planning.

Heist Structure

The Diamond Casino Heist is a bit different from previous heists in GTA Online. There are several heist setup missions, and they will differ based on the approach you decide to take. Players can collect certain pieces of equipment, which will allow them to practice elements of the heist, to increase their likelihood of success.
As long as your crew has shared lives remaining, failure isn't the end. Failing specific scenarios will not mean the end for the heist as a whole, but rather shift the team into a new scenario.

Heist Setup Missions

There are several heist prep missions, and they will differ based on the approach you decide to take.
Setup missions can be launched from the Heist Setup Board in the Underground Hideout, and revolve around intel acquisition. These missions can be used to gather information and equipment to aid in the heist.

Once players have completed the one-time missions, they will need to choose a Heist approach.

Silent & Sneaky: Players attempt to enter the vault undetected, giving them the least resistance and the longest amount of time to steal from the vault.
The Big Con: Players attempt to enter the vault by passing themselves off as workers, creating minimal resistance and requiring finesse.
Aggressive: Players attempt to enter the vault by force, using weapons to overcome extreme levels of resistance.

After an approach has been chosen by the Heist Leader, heist prep will begin.

Heist Prep Missions

Heist Prep will change, based on the heist approach chosen by the group leader, and which ones are completed will determine the various bonuses, equipment, weapons, vehicles and crew they will have access to in the Heist Finale.

Players will be able to select their Heist Crew based on various factors, with each one contributing a particular skillset to the job.

Heist Finale

Once players have picked their approach and completed prep missions, the Heist Leader can initiate the finale.

NOTE: The Heist Finale requires 2-4 players to initiate.

After finalizing details and choosing the location of the Buyer, the Heist Finale will begin. This stage will vary wildly based on the approach chosen, the particular intel players gathered, and the equipment obtained during the Setup phase.
